July Seminar
Comparative Analysis of RGB-MiniLED TV vs QDEF TV

Presentation Abstract
Since the introduction of a 116-inch RGB MiniLED TV by Hisense at CES 2025, many TV brands have released their products based on the RGB MiniLED implementation. The technology promises several advantages, including a wider color gamut, improved viewing experience and reduced power consumption.
However, full-array RGB LED backlighting is not a new concept. As early as 2004, Sony introduced the first TV employing a full-array RGB LED backlight to enhance color reproduction and dynamic contrast. Despite its technical merits, the approach did not gain widespread adoption due to challenges such as high cost and differential aging of the RGB LEDs. Because red, green, and blue LEDs degrade at different rates under same operating conditions, color shifts can occur over time. This non-uniform aging may also contribute to visible image artifacts, such as the so-called “dirty screen effect,” particularly when displaying white or near-white content.
Can the latest RGB MiniLED implementations deliver on their promised benefits? More importantly, can they overcome the challenges that limited adoption more than two decades ago?
In this talk, we examine the current RGB MiniLED implementation and conduct a comparative analysis against the de facto wide-color-gamut TV solution: MiniLED backlighting with quantum-dot enhancement film (QDEF). We evaluate the strengths, limitations, and practical trade-offs of both approaches to assess whether RGB MiniLED represents a meaningful advancement in LCD TV technology.
